A comparative study of using random switching schemes for DC/DC converters
This paper addresses a comparative investigation on the use of random modulation schemes for DC/DC power converters. The modulation schemes under investigation include randomized pulse position modulation, randomized pulse width modulation and randomized carrier frequency modulation with fixed and variable duty cycle. The study emphasizes the suitability and applicability of each scheme in DC/DC power converters, the randomness level on the effectiveness of spreading the dominating frequencies in constant frequency pulse width modulation scheme, and the low-frequency power spectral density (PSD) of each scheme. Validity of analyzes is confirmed experimentally by using a DC/DC buck converter, where the PSD of the output for each scheme is presented.
